1关键天体反应18Ne(α,p)21Na的实验研究显示文摘在X射线暴高温高密度的环境中,18Ne(α,p)21Na很可能是由热CNO循环突破到rp过程的一个重要反应。到目前为止,人们测得的反应率还存在很大的不确定性。实验中用CRIB(CNS Radioactive Ion Beam separator)提供的21Na放射性束轰击8.8 mg/cm2的聚乙烯厚靶,利用放置在θlab=-14°,0°,14°处的3套硅条探测器望远镜阵列对反冲轻粒子进行鉴别和测量,测得在一段能区(Ex=5.5~9.2MeV)内21Na(p,p)21Na的激发函数。通过对21Na(p,p)共振弹性散射截面进行R矩阵拟合,得到了22Mg共振能级的自旋宇称以及质子宽度等信息,从而为计算18Ne(α,p)21Na反应率提供了实验参数。张立勇 许世伟 何建军 H.Yamaguchi S.Kubono Y.Wakabayashi: 陈思泽 胡钧 马朋 Y.Togano T.Hashimoto D.Kahl T.Teranishil 陈若富 王宏伟 田文栋 郭冰 S.Hayakawa N.Iwasa T.Yamada T.Komatsubara 2013原子核物理评论2013,30,4:1
2Measurement of 2H(12N, 13O)n Angular Distribution and Determination of Astrophysical 12N(p, γ)13O Reaction Rate显示文摘The evolution of massive stars with very low-metallicities depends critically on the amount of CNO nuclides which they produce. The 12N(p, γ)13O reaction is an important branching point in the rap processes, which are believed to be alternative paths to the slow αp process for producing CNO seed nuclei and thus could change the fate of massive stars. In the present work, the angular distribution ofGUO Bing SU Jun LI Zhi-hong WANG You-bao YAN Sheng-quan LI Yun-ju SHU Neng-chuan HAN Yin-lu BAI Xi-xiang CHEN Yong-shou LIU Wei-ping H.Yamaguchi D.N.Binh T.Hashimoto S.Hayakawa D.Kahl S.Kubono HE Jian-jun HU Jun XU Shi-wei N.Iwasa N.Kume LI Zhi-huan 2012Annual Report of China Institute of Atomic Energy2012,,1:0
3Resonant Scattering of 22Na+p by Thick-Target Inverse Kinematic Method显示文摘22 Na is one of the most important yet debatable cosmic γ-ray emitters. The relative short half-life of 22 Na (T1/2=2.6 a) and the delayed 1.275 MeV γ-ray indicate that the 22Na may be a very sensitive probe to the nova outburst, especially for the nearby ONe novae from the Sun.WANG You-bao JIN Sun-jun SU Jun YAN Sheng-quan LI Yun-ju GUO Bing LI Zhi-hong BAI Xi-xiang LIU Wei-ping H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama H.Iwasa H.Komatsubara 2012Annual Report of China Institute of Atomic Energy2012,,1:0
4Neutron and Alpha Structure in Neutron Deficient Nuclei in Astrophysics显示文摘The paper includes discussions on the important role of neutron and alpha configurations in proton-rich nuclei in nuclear astrophysics in terms of nucleosynthesis under extremely high-temperature hydrogenburning conditions. The νp-process, which is supposed to take place at the very early epoch of type II supernovae, has considerable neutrons and alphas together with protons. The alpha-induced reactions on proton-rich unstable nuclei in the light mass regions is expected to play a crucial role, but very few of them were investigated well yet because of the experimental difficulties. Specifically, I report our recent experimental effort for the breakout process from the pp-chain region,~7Be(α, γ)^(11)C(α,p)^(14)N under the νp-process. The neutron-induced reactions on proton-rich nuclei, which is even more a challenging subject, were investigated previously for very few nuclei. One possible experimental method is the Trojan Horse Method(THM). We successfully have applied THM to the ^(18)F(n,α)^(14)N reaction study with an unstable beam of ^(18)F.S.Kubono 何建军 H.Yamaguchi D.M.Kahl S.Hayakawa T.Teranishi S.Cheribini M.Gulino Y.K.Kwon T.Hashimoto Y.Wakabayashi N.Iwasa S.Kato T.Komatsubara D.N.Binh L.H.Khiem N.N.Duy T.Kawabata C.Spitaleri G.G.Rapisarda M.La Cognata L.Lamia R.G.Pizzone S.Romano A.Coc N.de Sereville F.Hammache G.Kiss S.Bishop 2016原子核物理评论2016,33,2:0

8Study of Proton Resonances in ^(22)Mg by Resonant Elastic Scattering of ^(21)Na+p and Its Astrophysical Implication in ^(18)Ne(α,p) ^(21)Na Reaction Rate显示文摘Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separator(CRIB) and bombarded a thick(CH2)n target. The energy spectra of recoiled protons were measured at scattering angles of θcm ≈172° and 146°,respectively. A new state at 7.06 MeV has been observed clearly and another new one at 7.28 MeV is tentatively identified due to its low statistics. The proton resonant parameters were deduced from an R-matrix analysis of the differential cross section data. The astrophysical resonant reaction rate for the 18Ne(α,p)21Na reaction has been estimated,and it is about five times larger than that assumed before.S.Kubono T.Teranishi M.Notani H.Baba S.Nishimura J.Y.Moon M.Nishimura S.Michimasa H.Iwasaki Y.Yanagisawa N.Hokoiwa M.Kibe J.H.Lee S.Kato Y.Gono C.S.Lee 2009原子核物理评论2009,26,S1:0
9~1H(^(17)F,α)^(14)O反应截面测量显示文摘^(14)O(α, p)^(17)F是天体X射线暴中重要的突破反应。本工作通过厚靶方法测量其逆反应~1H(^(17)F,α)^(14)O的反应截面来研究这一关键反应。本实验工作是在日本东京大学原子核科学研究中心(CNS)的低能次级束流线(CRIB)上完成的,后续的扣除本底实验是在兰州放射性束流线(RIBLL1)上完成的。CRIB实验是通过~2H(^(16)O,n)^(17)F转移反应产生^(17)F次级束,经过CRIB分离提纯之后,利用该次级束轰击氢气靶。在氢气靶后布置了三套望远镜探测器系统,用以探测不同实验角度的反冲α粒子,在数据处理的过程中经过动力学重构后得到了~1H(^(17)F,α)^(14)O反应在质心系能区E_(c.m.)=2.7~3.4 MeV的反应截面。实验结果在3 MeV以上的高能区与前人的薄靶实验数据是一致的,在低能区本工作获得了新的实验数据,倾向于支持干涉相消的理论预言结果。贾宝路 胡钧 何建军 许世伟 H.Yamaguchi D.Kahl 马朋 苏俊 王宏伟 T.Nakao Y.Wakabayashi T.Teranishi K.I.Hahn J.Y.Moon H.S.Jung T.Hashimoto A.A.Chen D.Irvine C.S.Lee S.Kubono 2019原子核物理评论2019,36,1:0

11用逆运动学厚靶方法研究22Na+p共振散射显示文摘正22Na是最重要但又有争议的宇宙γ射线发射体之一,其相对较短的衰变寿命(T1/2=2.6a)及其缓发的1.275MeVγ射线,使其有可能成为太阳系附近ONe新星爆发的灵敏探针。在新星形成过程中随温度提高有两种模式,即20Ne(p,γ)21Na(β+)21Ne(p,γ)2Na或20Ne(p,γ)21Na(p,γ)22Mg(β+)22Na可生成22Na,王友宝 金孙均 苏俊 颜胜权 李云居 郭冰 李志宏 白希祥 柳卫平 H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama N.Iwasa H.Komatsubara 2012中国原子能科学研究院年报2012,,1:0
